Driving the PCB Manufacturing Revolution: UGPCB Introduces Nationally Certified PE19-3052 Inline Plasma Desmear System
In the era of high-speed, high-density electronics, the reliability of a high-performance Leiterplatte (Leiterplatte) begins in the microscopic world invisible to the naked eye. The cleanliness of drilled hole walls is fundamental, directly determining the quality of subsequent metallization and forming the cornerstone of a PCB’s electrical performance and long-term reliability. Traditional chemical wet desmear processes are increasingly becoming a bottleneck for high-end Leiterplattenherstellung in terms of environmental impact, kosten, and consistency.
Heute, this paradigm has been fundamentally transformed. As a leading PCB and PCBA manufacturer, UGPCB has proactively integrated the “PE19-3052 Fully Automatic Inline Plasma Desmear System,” developed by Zhuhai Hengge Microelectronic Equipment Co., Ltd. The technology underpinning this equipment has been recognized by China’s Ministry of Industry and Information Technology (MIIT) as part of the inaugural list of “Advanced and Applicable Technologies,” marking a landmark achievement in the PCB industry’s green and high-end transformation. This is more than an equipment upgrade; it is a firm commitment from UGPCB to providing “high-reliability PCB solutions” and advancing next-generation advanced PCB manufacturing processes.
Part 1: Breaking with Tradition: The Technological Leap from Chemical Wet to Physical Dry Processing
In the manufacturing of multilayer and high-layer count PCBs, heat from drilling creates a layer of insulating “smear” on the hole wall epoxy resin. Incomplete removal leads to poor hole metallization, causing potential critical defects like open circuits and board delamination. For decades, the industry relied on the wet process of permanganate chemical desmear—a lengthy sequence involving “swell → desmear → neutralize” Schritte, generating vast amounts of COD (Chemical Oxygen Demand) laden wastewater.
The Hengge PE19-3052 system brings a fundamental revolution. It employs dry plasma treatment technology, using Radio Frequency (Rf) energy to ionize process gases (z.B., mixtures of oxygen, Stickstoff, carbon tetrafluoride), creating highly active plasma. These energetic particles bombard the hole walls, precisely stripping and vaporizing the resin smear through physical sputtering and chemical reactions, achieving simultaneous cleaning and activation.
A comparative formula highlights its superiority:
Traditional Wet Process Cost (C_wet) ≈ Chemical Costs + Water Treatment Costs + Energy Costs + Time Costs + Safety/Compliance Costs
Plasma Dry Process Cost (C_dry) ≈ Electricity Cost + Process Gas Cost
When C_dry << C_wet and quality factor Q_dry ≥ Q_wet, technological substitution becomes inevitable.
The system adopted by UGPCB is the optimal implementation of this formula. Integrated directly at the front end of existing Plated Through-Hole (PTH) lines, it enables seamless PCB automated production, completely replacing the traditional wet desmear stage and eliminating the use and associated risks of strong oxidizers at the source.
Part 2: The PE19-3052 System: Defining Precision and Efficiency in High-End PCB Fabrication
The PE19-3052 is not merely a functional replacement; it is a high-precision production unit engineered for modern smart PCB factories. Its core design tackles the industry challenge of uniform treatment for large-format, high-layer-count boards.
1. Superior Hardware Design Ensures Consistency
The core plasma chamber utilizes aerospace-grade seamless welding, ensuring exceptional vacuum integrity with a leak rate below 10 mt/min, forming the foundation for a stable plasma environment. Its innovative “multi-grid electrode structure” and high-efficiency RF electrode design achieve over 85% treatment uniformity even for oversized panels (easily handling large boards like server motherboards), decisively solving the pain point of disparity between edge and center results. One-piece electrode forming and removable panel designs further ensure long-term operational stability and ease of maintenance.
2. Deep Integration of Intelligence and Automation
The system perfectly aligns with Industry 4.0 principles. It automatically synchronizes with PTH line speed for unattended continuous production. Integrated high-precision sensors and an intelligent control system monitor and dynamically adjust dozens of parameters—process gas mixture, RF power, vacuum level—in real-time, ensuring every board and every hole meets stringent preset standards. This provides critical data support and closed-loop process control capability for UGPCB’s fully digitalized Leiterplattenfertigung ecosystem.
3. Inherent Green Manufacturing for the Future
Green manufacturing is a core competency for high-end PCB production. The PE19-3052 system achieves pollution and carbon reduction at the source. According to MIIT-disclosed techno-economic indicators, for a PTH line with a daily capacity of 10,000 square feet, this technology can save approximately 1.79 million RMB annually in operational costs alone. More significantly, it enables:
-
Zero Chemical Wastewater Discharge: Permanently solving the permanganate wastewater challenge.
-
Exceptionally Low Energy Consumption: Significantly lower compared to the multiple rinse and heating tanks of traditional processes.
-
Enhanced Safety: Creating a work environment free from chemical exposure risks for operators.
